I don't know how this stuff works, what gives google the ability to sell these domains early? Also why is everyone cursing google for taking their local .dev? Google is not the only place you can buy these. Namecheap has .dev in the works, and GoDaddy is taking pre-orders as well (I didn't keep searching but I'm sure it's available at many other registrars), but nobody is cursing and shaking their fist in the air at those services. So what does google have to do with it? Why are we all holding them responsible?
